1. Introduction
This document is essential reading for whoever is responsible for the
installation of the NAG fl90 implementation specified in the title. The
installer will be supplied with a printed copy of this document. Both this
and the Users' Note are supplied on the distribution medium.
Whenever the NAG fl90 library has been supplied in compiled form, that form
is considered to be the standard library file. The use of all supplied
software must be in accordance with the terms and conditions of the Software
Licence signed by NAG and each site. In particular, users must not have free
access to the text of the library routines. Any request to use NAG software
on a computer other than the one licensed must be referred to NAG (see
Section 6).
2. Implementation Provided
2.1. Applicability
This implementation is a compiled, tested, ready-to-use version of NAG
fl90 that is considered suitable for operation on the computer systems
detailed below:
hardware: IBM RISC System/6000
operating system: AIX v4.1
Fortran compiler: IBM xlf90 v3.2
An implementation of NAG fl90 using the NAGWare f90 compiler is also
available.
For information about implementations of NAG fl90 for use on other
computer systems please contact NAG.
2.2. Derivation
This implementation was produced at NAG Ltd., Oxford on the computing
system detailed below:
hardware: IBM RISC System/6000 Model 530H
operating system: AIX v4.1
Fortran compiler: IBM xlf90 v3.2.4
The entire NAG fl90 library was compiled with full optimization (-O3),
except for the following underlying procedures, which had to be
compiled with reduced optimization (-O2):
f08sax_9dt.f90 f08sox_9dt.f90
The Library was also compiled with the compiler option -qarch=com,
to specify that the Library should be suitable for all types of RISC
systems.
3. Distribution Medium
3.1. Recording Details
The implementation is distributed in tar format on CD-ROM, unless
otherwise indicated on the medium and accompanying despatch note.
For further details, refer to other documentation supplied or contact NAG
(see Section 6).
3.2. Contents
The following shows the directory/file organization of the materials on
the distribution medium. A brief description of some of the files is
given.
|-- in (Installer's Note)
|-- doc --|-- *.3 (man pages)
| |-- *.html (HTML pages)
| |-- images --|-- *.gif (image files for HTML
| pages)
|
|-- libnagfl90.a (compiled library)
fnib603db --|
| |-- source ---|-- *.f90
|-- examples --|-- data -----|-- *.dat
| |-- results --|-- *.r
|
|-- source --|-- c?? --|-- *.f90
|
|-- nag_mod_dir --|-- *.mod (modules which provide
| essential information to NAG
| fl90 and which allow the
| Fortran 90 compiler to check
| that procedures are called
| correctly)
|
|-- scripts --|-- nagexample (a shell script to run example
programs)
3.3. File Sizes
The files require approximately the following disk space:
compiled library: 9.3 Mb
example program material: 1.1 Mb
module information files: 7.6 Mb
documentation files: 0.5 Mb
library source code: 10.7 Mb
(not needed on disk permanently)
4. Library Installation
4.1. Installation
To install all primary material (to be made available to users), use
the UNIX tar utility to read documentation, compiled libraries, module
information files and examples, e.g.
tar xvf /cdrom/fn03.tar fnib603db/doc fnib603db/libnagfl90.a \
fnib603db/nag_mod_dir fnib603db/examples \
fnib603db/scripts/nagexample
(assuming the CD-ROM has been mounted as /cdrom).
The object library (libnagfl90.a) should be moved to either /usr/lib or
/usr/local/lib, if possible, so that linkage is convenient.
The module information files (nag_mod_dir/*.mod) are supplied in
pre-compiled module form. They should be moved to a suitable location
so that access is convenient, e.g.
mkdir /usr/local/lib/fl90_modules
mv nag_mod_dir/* /usr/local/lib/fl90_modules
The -I"pathname" option should then be specified on each f90 invocation
(where "pathname" is /usr/local/lib/fl90_modules) to tell the compiler
where to find the modules.
The script nagexample refers to the local directory containing the
example programs. The file should be copied to (for example)
/usr/local/bin, modified to reflect the local installation, and its
protection set to world execute.
The man pages should be moved to the appropriate directory. All pages
belong in section 3 of man, e.g.
cd doc
mv *.3 /usr/local/man/man3
To install all material (including source) use the UNIX tar utility,
e.g.
tar xvf /cdrom/fn03.tar
Source should be needed only for reference by whoever is responsible
for the installation of the library. This material should not be made
available to users.
4.2. Checking Accessibility
The installation can be tested by using the script nagexample (when logged
in as a normal user). The script will copy an example program and its
data, compile it, link it with the library and run it. For example, give
the command
nagexample nag_lib_support_ex01
4.3. Release to Users
The supplied Users' Note should be checked and amended as necessary
(particularly the section "Accessing the Library").
The Users' Note is provided in man page form in nag_fn_un.3.
The following material should also be made accessible to users:
compiled library:
libnagfl90.a
example program material:
examples/source/*.f90
examples/data/*.dat
examples/results/*.r
scripts/nagexample
module information files:
nag_mod_dir/*.mod
documentation files:
doc/*.3
doc/*.html
doc/images/*.gif
Making the supplied example material directly available to users provides
them with easily adaptable templates for their own problems.
5. Additional Services from NAG
(a) Documentation
Each NAG fl90 site is provided with a printed copy of the NAG fl90
Manual. Additional manuals are available at prices published in the
NAG documentation order form.
NAG fl90 TextWare, a hypertext version of the full manual, is bundled
with this implementation. For a list of supported platforms, see the
Installer's Note for the TextWare product.
